Just updated from fedora 18 to 19 -- mostly trouble-free and very impressive.

One issue: when I boot up this is what happens:

1) grub does its thing; I let it time out to the default; OK.

2) plymouth starts: the little expanding white teardrop thingy that will turn into the "f" logo; OK.

3) About 15% percent into the expansion (a second or two), video output quits altogether. Black screen, and my monitor posts its "No video input" message.

The first time this happened I thought the system was screwed, but actually if I wait 10 seconds or so, video comes back with the login screen.

This is on a Dell XPS box with Radeon HD 6450 video. No such problem with fedora 18.

First thing is to check the log files for clues. Look at /var/log/Xorg.0.log and /var/log/boot.log and the dmesg output.

Thanks for the suggestions. But (1) there's no indication of a problem in Xorg.0.log. This is not very surprising to me, since my understanding is that Xorg starts after plymouth is finished. And (2): are you sure that boot.log is a "current" file? On my system the last boot.log entry was written by fedora 17 in July of last year; it seems that fedora 18 and 19 don't touch it.

Also, when the fedora balloon logo starts filling in, press ESC and see if it shows any error!

Pressing ESC gives me a text screen which does not go black like the balloon, but which does not show any obvious errors. I could post the log as supplied by journalctl but I'm not sure how to do that in this forum.

You can post the log file to http://fpaste.org and link it here. 'journalctl -b' output would indeed be the most comprehensive and useful, it might also be useful to post the Xorg.0.log. So, if you press esc during boot, you don't see a long screen blank? Is boot actually faster than if you don't?
